671599 divided by 5 
We're looking to find how many times 5 goes into 671599.

Going ahead to step 1:
If we divide 6 by 5, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 5 from 6 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 5

On to step 2:
The number 5 fits into 17 3 times, leaving a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 15 from 17 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 5

Advancing to step 3:
21 divided by 5 is 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 134.0
Deduct 20 from 21 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 5

Moving on to step 4:
15 divided by 5 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 1343.0
If we take 15 away from 15, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 5

On to step 5:
9 divided by 5 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 13431.0
Subtract 5 from 9 to get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 5

Let's proceed to step 6:
The number 5 fits into 49 9 times, leaving a remainder of 4.
The next digit of our result is 9. 
Result so far: 134319.0
The remainder is 4 after subtracting 45 from 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
5 goes into 40 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 134319.8
Subtract 40 from 40 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 5 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 134319.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
If we divide 0 by 5, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 134319.8
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 134319.8 and a remainder of 0.0.
